IMPROVEMENT IN MOP AND BRUSH HOLDERS.

Specification forming part of Letters Patent No. 167,304, dated August 3l, 1875 application filed August 4, 1875.

To all whom t may concern Be it known that I, CHARLEs B. CLARK, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Combined Mop and Brush Holder, of which the following is a specification:

My invention relates to that class of holders in which the mop-cloth or brush .is clamped by means of a pivoted jaw shutting against a fixed jaw, to which is attached the ordinary wooden handle.

The object of my improvement is to construct a device that shall effectually clamp and hold either a mop-cloth or brush, as may be desired, and to have the requisite strength so proportioned as to form a light, compact, and symmetrical article, and capable of being readily and easily adjusted.

My invention consists in providing the arm ofthe hinged jaw with a curved extension or lever, upon which a thumb-nut, traversing the screw ofthe fixed jaw, presses with sufficient force to clamp the jaws together, and in such manner that the said thumb-nut will overlap or inclose the end of said curved lever in such manner that there will be no projecting point or points which are liable to interfere with the perfect working ofthe mop.

In the accompanying drawings, Figure l represents a perspective view of my invention 5 Fig. 2, a vertical section of the same, and Fig. 3 a view showing the manner of holding` the brush in position.

The fixed jaw a terminates in a socket, c, which has on its exterior a screw-thread, and carries a thumb-nut, e. The hinged jaw b is pivoted to the shank of the fixed jaw a, through the mortise by the rivet d. As shown in Fig. l, the jaws a and Z) are closed by means of the thumb-nut 6 rotating upon the screw-shank, and pressing upon the curved portion of the lever j. rIhis lever is an extension of the arm of the jaw b, and being placed the perfect working-of the holder, as the curved lever is depressed within the mortise of theshank. The jaws a and b are concave on their inner sides, as at 7c k, in order to give ample room for clamping the mop-cloth or brush, and at the same time strengthening the jaws. Each of said jaws is provided with an upper and a lower row of teeth or projections, f g. The upper teeth j' are curved, and, fitting into each other, serve to bind and hold the cloth firmly, and they are further assisted by the lower teeth g, which shut together at their points. When used as a brush-holder the outer teeth clamp, while the back ofthe brush rests against the inclined surfaces of the lower teeth, as shown in Fig. 2. Ribs h 7L extend around both the inner and outer sides of the curved portions of the jaws a b, and act as braces to strengthen the clamping parts. By the use of these ribs a saving of material is effected without decreasing' the strength, as it is desirableto have the holder light and portable.

rllhe several parts of my improved holder are easily cast,'and require no drilling, as the rivet-holes are made in the process of molding, and, the parts being light and well proportioned, I am enabled to produce a strong and superior article, while the cost of the production is much less than in mops of this particular class as heretofore constructed.

Having thus described my invention, what Y I claim, and desire to secure by Letters PatrIhe combination, with the fixed jaw a, having a slotted screw-threaded shank, fi, and a thumb-nut, c, applied thereto, of the movable jaw b, pivoted Within said slotted shank7 and having its rear end constructed with a lever, j, on which the nut operates, s'o that said rear end is encircled by the nut, andforced to enter the slot by tightening said nut, substantially as and for the object specified.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.
